This manuscript is devoted to quantization problems in mathematical and theoretical physics. It is divided into two subjects: conformally invariant fields on de Sitter spacetime and quantization through coherent states. • The first subject follows a comprehensive program of covariant quantization of fields in de Sitter spacetime, whose spirit is close to the Wightman axiomatic. We paid a particular attention to the quantization of fields that could be (naturally) extended to the conformal group. We developed a geometric point of view enabling us to link fields on (anti-)de Sitter and Minkowski spacetimes while keeping transparent the action of the conformal group. This geometric viewpoint led us to the expression of a new propagator for the...
